Hame-fastener.



WILLIALI M. CASWELL AND JOSEPH A. SCHOFIELD, 0F 'W'ARREN, PENNSYLVANIA.

HAlVIE-FASTENER.

Specification of Letters Patent.

Patented June 21, 1910.

To all whom it may concern:

Be it known that we, I/VILLIAM M. Ons- WELL and J osnrrr A. SCHOFIELD,citizens of the United States, residing at \Varren, in the county ofWarren and State of Pennsylvania, have invented certain new and usefulImprovements in I-Iame- Fasteners; and we do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in hame fasteners.

The object of the invention is to provide a hame fastener which will besimple, strong and durable in construction, and by means of which thehames may be quickly and firmly secured to the collar, and having meanswhereby the same may be readily engaged with and released from the lowerends of the hames.

Vith this and other objects in View, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claim.

In the accompanying drawing, Figure 1 is a side view showing the mannerof engaging the device with the hames; Fig. 2 is a top plan view of thefastener; Fig. 3 is a vertical longitudinal sectional view; and Fig. 4is a vertical cross sectional View, taken on a line with the pivot ofthe operating lever.

In the embodiment of the invention we provide a supporting frame whichpreferably consists of a pair of segmental plates, 1, which are spacedapart and held together in parallel relation by means of connectingbars, 2, arranged thereon adjacent to their opposite ends. In one end ofthe frame is arranged a cross bar, 3, to which is connected an attachinglink, 4, .with which is engaged a hame attaching member, 5, which ispreferably in the form of a double hook, the ends of which are held inoperative engagement with the link, 4, and the end of one of the hamesby a cotter-pin, 6, or other suitable fastening device. To the link, 4,is also connected a short chain or series of links, 7 with any one ofwhich links the hame, 5, may be engaged to lengthen the connectionbetween the fastener and the end of the hame when desired.

Midway between the opposite ends of the frame plates 1 is arranged apivot bolt, 8, on which is pivotally mounted a cam operating lever, 9,to the cam-shaped head of which is eccentrically pivoted the inner endof a fastening member, 10, said member being preferably formed ofparallel bars, 12, one of which is arranged on each side of the cam headof the operating lever.

The outer ends of the bars, 12, have formed therein a series of alinedapertures and between said ends is secured a hameengaging hook, 14, theshank of which is provided with one or more apertures which are adaptedto be alined with certain of the apertures in the bars, 12, and throughsaid apertures is inserted a fastening pin, or pins, 15, by means ofwhich the hame is ad justably secured to the end of the fasteningmember.

The upper edges of the bars 12 of the fastening member 10 are recessedand are adapted to engage stop lugs 13 arranged on opposite faces of thecam head of the lever 9 when the latter is in operative position asshown in Figs. 1 and 3, and the hook 14 in hame engaging position, thusholding the fastening member 10 and lever 9 against -relative movement.

The engagement of the inner ends of the bars, 12, of the fasteningmember with the cam head of the operating lever is such that when saidlever is swung in one direction, the fastening member, 10, and hook, 14,will be projected or extended beyond the end of the frame, thuspermitting the hook 14 to be readily engaged with or disengaged from theend of the adjacent hame. After the hook, 14, has been engaged with theend of the hame, the operating lever is swung around in the oppositedirection to cause the cam head thereon to retract the fastening memberand thereby draw the hame into tight engagement with the collar. Afterthe lever has been operated to draw the hame into engagement with thecollar, the lever is locked to hold the parts in this position by meansof a bail, 16, which is pivotally connected with the cross bar, 3, anddepends therefrom. The locking bail, 16, is pre vented from becomingcasually disengaged from the end of the operating lever by means of alug, or stop, 17 which is formed on the lower side of the lever adjacentto its outer end.

In the arrangement of the parts as herein shown and described, the crossbar, 2, at

one end ofthe frame serves as asupport' and guide for the fasteningmember when actuated by the operating lever; The cross bar, 2, at theopposite end of the frame serves as 5 a stop to limit the upwardmovement of the' outer end of the operating lever when the latter isswung into-position for retracting the fastening member.

From the foregoing description, taken in 10 connection withitheaccompanyingdrawing,

the construction and" operation of theinvention will=be readilyunderstood without requiring amore extended explanation.

Having thus described our invention, what 15 We claim as new and desireto secure by Letters-Patent, is:

A hame fastener comprising a supporting frame consistmg of a pairof-correspondlng plates, an operating lever having a cam- 9 head,pivoted between said plates, a faste n ing member comprising apair ofparallel bars having recessed upper edges pivoted'at their inner ends tothe cam head of'said lever, a hame engaging hook adjustably connectedwith the outer ends of said fastening bars, a bail pivoted to one end ofthe frame andadapted to engage and support the free end of the operatinglever in operative pos1- tion, means for connecting the adjacent end Intestimony whereof we have hereunto 7 set our hands in presence of twosubscribing witnesses.
